The distance around a circle---it's circumference---or the length of some portion thereof---a segment---is measured in linear distance units such as inches, centimeters, feet, or meters.
The portion of a circle (the relative distance around) that a segment represents---the segment's circular arc---is measured in units of angular magnitude. In basic geometry and lay usage, the most common angular unit is the degree. In scientific and higher math usage, the most common unit is the radian. The circumference of a circle has an arc of 360° (360 degrees), or 2π rad (2 × pi radians). A radian therefore is equivalent to 180/π degrees. Other units of angular magnitude include the turn (360° or 2π rad), grad (aka gon; 1/400 turn), quadrant (1/4 turn), arcminute (1/60°), and arcsecond (1/60 arcminute).

What is a unit that measures distances around a circle?
There is no special unit related to the distance around a circle. It's a distance, a length measurement.Pick what fits. Millimeters, inches, yards, kilometers....It's possible to describe it in degrees too, referring to the width of an angle as seen from the center.Rarely used outside fairly specialized navigation purposes.
When was it confirmed that there was 360 degrees in a circle?
It was never confirmed. The degree was created as a unit equal to one three hundred sixtieth of the way around a circle
What is the circumference of a unit circle?
Since the radius of the unit circle is 1, the circumference is 2 x pi.
What is a cube whose edges measure 1 unit?
A 'unit cube'. Just like a circle with radius 1 and center at (0,0) is a 'unit circle'.
Find all the coordinates of the points on unit circle?
If x2 + y2 = 1, then the point (x,y) is a point on the unit circle.

How can the unit circle be used to apply trigonometric functions to all real numbers?
The basic idea is that a complete turn around the unit circle has a length of 2 x pi (i.e., approximately 6.28). For numbers larger than 2 x pi, you go that distance around the unit circle, moving around it more than once - and eventually end up on some point on the unit circle. For example, if you go a distance of 3 x pi around the unit circle, that is equivalent of a distance of pi (equal to 180 degrees). For negative numbers, you simply move around the unit circle in the opposite direction.
What is the unit used to measure distances around a circle?
The distance around a circle is its circumference and it can be measured in any linear units.
What is the difference between the unit circle and imaginary unit circle?
A unit circle is in the coordinate plane where both axes are measured in real numbers. The imaginary circle is in the complex plane in which one axis (horizontal) measures the real component of a complex number and the other axis measures the imaginary component.
What measuring unit measures length or distance?
ruler
Which unit measures distance across an ocean?
Mile
How many liters are in 500 millimeters?
A litre is a unit of capacity. A mililmetre is a unit of distance. The two units are therefore incompatible.
What unit most likely measures the distance traveled by a truck?
Kilometres.
What unit measures the shortest distance?
The shortest SI unit of length is a yoctometre - there are 1000000000000000000000000 of them in one metre.
What Measures distance north and south from the eqautor?
What unit of longitude and latitude measerment
An ant starts at the point 0 1 on the unit circle and walks around clockwise a distance of 6 units around the circle Find the x and y coordinates of the final location of the ant?
The ant is at (-0.2794, 0.9602)
Are kilometers English or metric measures?
The 'kilometer' is a unit of length or distance in the metric system.
